SPECIFICATION forming part of Letters Patent No. 432,597, dated July 22,1890.

Applicationviled October 25, 1889. Serial No. 328,148. (No model.)

To all whom it may con/cern.:

Be it known that I, JOSEPHv N. BROWN, a citizen of the United States,residing at Farwell, in the county of Clare and State of Michigan, haveinvented certain new and useful Improvements in Hand Veighing- Trucks;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to weighing handtrucks; and it consists incertain improvements in the construction of the same, as hereinafterdescribed and claimed.v

In the accompanying drawings, Figure l is a plan view of a hand-truckprovided with my improvements, portions of the platform being brokenaway. Fig. 2 is a section taken on line o: n". of Fig. l. Fig. 3represents arear end view of the truck. Fig. 4. is an interior view ofthe register, the dial being mostly broken away. Fig. 5 is a sectiontaken on line y y of Fig. 4.

The frame of the truck consists of the side bars A, which are extendedto form the handles B, and the cross-bars o, c', and c2. A central rod bis iixcd to or in the said crossbars, and on said rod are placed thesprings d. Two other rods d d2 are fixed to the bars a a2, and havesprings placed on them, as shown. The platform C of the truck isvloosely connected with the frame bymeans of the perforated angle-ironsc, which Vare fastened to the lowerv side of the platform and areloosely connected with the rods I) d cl2, which are passed throughperforations inV placed on the central rod b just below the" cross-bara, the said block resting on a spring d and having vertical movement onsaid rod.

Two levers i are pivoted to the side bars A, one being secured to eachside bar and extending across the frame. nearly to the oppo* site bar A.These levers t' are connected by the short strips nv with the platform Con the under side, and are provided at their free ends with hooks whichare connected by rods m with the movable block h.

E indicates the casing of a registering device, which is secured to acurved bar F and is provided with a dial on which move theindicating-hands o. Vithin the casing is mounted a central shaft p,which carries a ratchet-wheel q, the hubV of which is provided withratchet-teeth r. A pinion S is loose on the shaft p, and a sleeve u onsaid shaft extends forward from said pinion and carries one of theindicating-hands o, the other hand being carried by the shaft p. Thelong hand indicates on. the dial the weight of a load and the other thenumber of loads weighed. A segment-gear t is pivoted in position tocngage the pinion s, and is connected by a rod u with a slotted bar w,which is connected at o with a cross-bar of the frame, the other end ofsaid bar 'lo being connected with the block 7L. A pawl s', which isconnected with the pinion s, engages the shaft j) by its con nectionwith the ratchet-teeth 7', an d a springpawl y, connecting with theratchet-wheel q, prevents a backward movement of the shaft p. The pawlss and y may be raised from the teeth o" on the hub of wheel q and pinions by means of a spring-rod to', a button z on the outer end of said rodbeing pressed.

I claiml. In a weighing-truck, the combination, with a frame and amovable platform, of a central rod, which is iixed to said frame andlooselyv connected with said platform, the spring on said rod, aperforated block placed loosely on said rod and supported by saidspring, two levers which are pivoted to the side bars of the frame, thestrips which conneet the said levers with the platform, two rods whichconnect the free ends of said levers with said perforated block and aregistering device, a slotted bar tu, which is pivoted to the frame andconnected with said perforated block, and the rod which connects roc theregistering meehanism with the slotted fi fi, and the pivoted strips nn, as and for the bau' fw, substantially is and for the purposes purposeset Vfori-h.

described. In testimony whereof I have affixed my sig- 2. Thecombination, with the platform C nature in presence of two witnesses.
